Daizyuzin (大獣神,Daijūjin?, Great Beast God): The combined form of the five primary guardian beasts, who first combine into the Beast Tank Dino Tanker (獣戦車ダイノタンカー,Jūsensha Daino Tankā?) and then transform further into Daizyuzin. Rather than a mere robot, Daizyuzin is actually a physical incarnation of the Ruling God of the five tribes. As such he has his own will and will occasionally give challenges or suggest the right actions for the Zyurangers to help on their quest to be real heroes.

First appearing in episode 6, Daizyuzin was shown to Geki during a vision of a post-apocalyptic future that Bandora would bring about if she were victorious. Under the instruction of Barza, Geki sought out the Dinocrystals (the key to combining the guardian beasts into Daizayujin) and after freeing his comrades from the trees Dora Sphinx had trapped them in along with several children, the five Zyurangers combined the guardian beasts into Daizyuzin to defeat both Dora Sphinx and Grifforzer before the children Dora Sphinx had imprisoned could be cut down by a construction crew.

When Burai was revived and given the Sword of Hellfriede, Daizyuzin told Geki to kill Burai. Geki refused and Daizyuzin was forced to punish him for letting his personal feelings override his duty as a Zyuranger. All was soon resolved when Geki finally managed to reach Burai's heart and Burai's tears destroyed the sword whereupon Daizyuzin officially announced that Burai would be the sixth Zyuranger. Prior to Burai's redemption, Bandora had learned of a prophecy of Daizyuzin's defeat and Grifforzer, Lamie Scorpion, and Burai worked together to hurl him into a lava pit as a solar eclipse had cut off Daizyuzin's power. Fortunately, the prophecy had only foreseen Daizyuzin's defeat rather than his death and after using the energy of the lava to reenergize, Daizyuzin returned in time to stop Dragon Ceasar from destroying the city while under Burai's control. After the destruction of Dora Talos and the death of Kai in the finale, Daizyuzin trapped Bandora and her lackeys in a golden vase and banished them back into the depths of space.

In battle, Daizyuzin wields the Mammoth Shield (マンモスシールド,Manmosu Shīrudo?), which can fire energy beams from its eyes and the Dinosaur Sword God Horn (恐竜剣ゴッドホーン,Kyōryūken Goddo Hōn?), which he uses in his Super Legendary Lightning Cut (超伝説雷光斬り,Chō Densetsu Raikō Giri?) finisher. He can also fire laser beams from his eyes, lightning from his crown, or energly blasts from the cannons on his back. Despite being a god, Daizyuzin was far from invincible as it was revealed during the battle with Satan Franke that in the initial battle with Dai-Satan, Daizyuzin's true form had been split into three lesser aspects (Daizyuzin, Dragon Ceasar, and King Brachion). After the Zyurangers performed a ceremony at an ancient alter where they "gave voice to their mission" Daizyuzin's full power was restored, enabling him to fight the new and more powerful Dokita-Dora Monsters on an equal level as well as to combine with Dragon Ceasar and King Brachion to form Zyutei and Ultimate Daizyuzin,

The first Guardian Beast to be awakened, the Guardian Beast Tyrannosaurus (守護獣 ティラノザウルス,Shugojū Tiranozaurusu?) is Geki's Guardian Beast and the god of the Yamato tribe. Bigger and stronger than the other primary Guardian Beasts, it is able to vaporize giant Dora Monsters with its Tyranno Sonic shockwave fired from its mouth and can stand on its tail to deliver jump kicks to its enemy. During the battle with Dora Sphinx in episode 5, rather than let Geki pilot him, Tyrannosaurus instead sent Geki into the future where he was confronted with the barren wasteland Bandora planned to turn the Earth into unless the Zyurangers learned to make their hearts as one. When Tyrannosaurus is called upon, he comes from under the earth. Forms Daizyuzin's head and body. First introduced in episode 2 and later helped out in Hyakujuu Sentai Gaoranger vs. Super Sentai.

The Guardian Beast ZyuMammoth (守護獣 ジューマンモス,Shugojū JūManmosu?) is Goushi's Guardian Beast and the god of the Sharma tribe. First introduced in episode 3. It can blow a glacial gas called Moth Blizzard of -200C from its trunk to freeze enemies. When ZyuMammoth is called upon, he comes from a glacial area. When the command Combine, Dino or Dragon Mission is given ZyuMammoth becomes DinoTanker's back, chest, and cannons; Daizyuzin's back, arms and Mammoth Shield; & Gouryuujin's back & arms.

The Guardian Beast Triceratops (守護獣 トリケラトプス,Shugojū Torikeratopusu?) is Dan's Guardian Beast and the god of the Etof Tribe. First introduced in episode 3. It is equipped with the dual Tricera Cannons on the tip of its tail and its two horns can be shot out on chains to ensnare giant opponents. When Triceratops is called upon, he comes from a desert area. Forms the left tread of DinoTanker, and both Daizyuzin's and Gouryuujin's left legs.

The Guardian Beast SaberTiger (守護獣 サーベルタイガー,Shugojū SāberuTaigā?) is Boi's Guardian Beast and the god of the Daim Tribe. First introduced in episode 3. Its running speed exceeds that of all the other Guardian Beasts. It also has a mighty laser gun called the Saber Gun on its tail and can slash opponents with its claws. When SaberTiger is called upon, he comes from a jungle area. Forms DinoTanker's right tread and Daizyuzin's and Gouryuujin's right legs.

The Guardian Beast Pteranodon (守護獣 プテラノドン,Shugojū Puteranodon?) is Mei's Guardian Beast and the god of the Risha Tribe. First introduced in episode 3. It is the only Guardian Beast with flying abilities, and its flying speed can go as high as Mach 2.5. It fires Ptera Beams from its wings. When Pteranodon is called upon, she comes from a volcano. Forms Daizyuzin's chest and DinoTanker's back. In the toy, her feet detach and form the barrels for DinoTanker's cannons.

When the five core guardian beasts first come together, they form into Beast Tank DinoTanker (獣戦車ダイノタンカー,Jūsensha Dainotankā?) which attacks enemies with its dual Beast Tank Cannons, or with lightning blasts from the eyes of each Guardian Beast called the Beast Tank Storm. When assuming the form of Daizyuzin; DinoTanker's cannons fold in to switch out with the hands, its front treads raise up to become the legs, Pteranodon detaches from the back and flies around to the front, and Tyrannosaurus' face folds into its chest to reveal Daizyuzin's head.

Video Game appearances

Zyuranger video game

DaiZyuzin appears in the Kyoryu Sentai Zyuranger video game. He appears in a Pong-style minigame with Dragon Caesar. In the main game, each of the five stages contains ten scattered coins which will replenish the player's life gauge completely when fully collected, as well display a still of the character's respective Guardian Beast and its specifications

Notes

Daizyuzin was the first Sentai Mecha to use a motif of prehistoric animals and was also the first to be comprised entirely of mechanized animals rather than vehicles. Liveman's LiveRobo included the mechanized Land Lion, however the other components-Jet Falcon and Aqua Dolphin-were both vehicles designed with animal motifs.
